Ok my 92 park ave doesn't have the lower break lights I don't know why I've changed the break. Controler behind the duct on the firewall both switches above the pedal any other suggestions are welcome.
lower break lights dont work but 3rd does on 1992 Buick Park Avenue
Have you checked the brake light bulbs and the check for power to the bulbs when the brake pedal is pressed? Check for power at the dark green/white wire at the right hand brake light and yellow/black wire at the left brake light.
Yes both dead
